Detection of heavy Majorana neutrinos and right-handed bosons

The SUc(3) x SUL(2) x SUR(2) x U(1) left-right (LR) symmetric model explains the origin of the parity violation in weak interactions and predicts the existence of additional gauge bosons W-R and Z'. In addition, heavy right-handed Majorana neutrino states N arise naturally within the LR symmetric model. The states N could be partners of light neutrino states, related to their nonzero masses through the seesaw mechanism. This makes the searches for W-R , Z', and N interesting and important. In the framework of the minimal LR model, we study the possibility to observe signals from N and W-R production in pp collisions after three years of running at low LHC luminosity. We show that their decay signals can be identified with a small background, especially in the case of same-sign leptons in the final state. For the integral LHC luminosity of L-t = 30 fb(-1), the 5 sigma discovery of W-R boson and heavy Majorana neutrinos N-e with masses M-WR up to 4 TeV and M-Ne up to 2.4 TeV, respectively, is found to be possible.
